BAND-FASTIENER.

SPECIFICATION forming part of Letters Patent No. 696,592, dated April 1, 1902.

Serial No. 631947. (No model.)

To @ZZ whom, tm/ty concern:

Beit known that I, GEORGE P. Rasoir, a citizen of the United States, residing at Des Moines, in the county of Polk and State of Iowa, have invented certain new and useful Improvements in Band-Fasteners, of which the following is a specification.

Myinvention relates to band-fasteners, and more particularly to that general class of fasteners which are especially adapted for use upon tanks and similar articles; and it has .fOl its Ob;l ect toimprove Aandsim plif y the construction of-such devicesyand to these endsit consists in. a fastem-n'` embodying the" features ofconstruction and arrangement of parts sub- 'tantiallyas `hereinafter more-particular] y set ,Referring totheaccompanying drawings,

s' Figure l is a plan` View showing the fastener in position.. Fig. v2 isa horizontal sectionon the line 2 2, Fig. 1;,andFig. is a transverse section-1 on the ,line l3,3, Fig. l, looking Yin @the direction of the arrow.

l-Ierctofore4 numerous devices have been made-.intended to, accomplis-h the' general ob` jects of my invention, yand,witho`ut pointing ont, specifically the constructions heretofore proposed' I willstate that experience shows that in a device of this character nitgistd'esirable that the lugsfshallfjbe{fastened-Fte the band at or near theouter e'nds Vof the lugs, as otherwise upon screwing up or bringing the lugs together, as by means of a bolt, the bolt will force the outer ends of the lugs outward, and the inner adjacent ends will be pressed into the tank or some of the staves of the tank, and it has been found difficult under these circumstances to tighten the bands satisfactorily. Furthermore, it is desirable that the bolt or other fastening'means connecting the lugs should be as near to the surface of the tank as possible, as in this Way a more direct pull or strain upon the bands is secured. Furthermore, it is desirable that the bands shall be held in the lugs by some quickly and easily adjusted devieesvwhich when in proper position will securely hold the ends of the bands in the lugs and which shall also permit the bolt to lie near the surface of the tank. These and other features of improvement which will appear hereinafter are met in the construction which l am about to describe.

Referring to the accompanying drawings, A represents a portion of a tank made up in the present instance of wooden staves d a a2, and .B B represent the ends of a band of metal or similar material passing around the tank, to which the lugs are attached and by means of which the band is tightened.. Each of the lugs is the complement of the other, and they can be used interchangeably, and therefore a description of one will'apply to both. `Thus there are shown two lugs C D,

each preferably `form ed of metahasphosphorbronze or similar material, and each 'provided with. what may be` termed a baseiportion C', which is" preferably curved slightly to conform tot-'he curvature of the tank, although if lthe tank'is of sufficient size this curvature needJ not' bejappreciable;r Rising fromthisjbase portion are upright sides C2, and extending from these-are theinclined -top portions G3, and extendinglongitudinally throughbthecenter is-,a cylindrical `.or arched portion G4, haying an opening,` C5 for the reception ofja suitablefbolt or'rodEt This opening-,is cylindrical at its ends,and there is across-,piece C'beneath the opening, and

ywhichhis arranged above 4the base portion C',

so Aastro form a longitudinal flat .slot or passage C7 for the recepticnof ,theend of the band. The sides of the arched portion extend downward, as at CS, into the plane of this slot and form practically a runway on each side between its ends and the upright sides C2, and in these runways are arranged rollers F F. A runway (shown in longitudinal section on the right-hand side of Fig. 2) is also formed by the inclined top C3 and a wall C, which is preferably beveled, as at C10, and the top C3 at the opening or inner end is provided with a toe or similar device C, which acts as a stop or retainer to hold the rollers F F in position and keep them from accidental displacement.

lt will thus be seen that each lug has practically two runways for the rollers, and in between them is an arched portion for the reception of the bolt, and this is brought down close to the base portion and is practically located between the runways, and the upper portion of the opening C5 therein extends but slightly above the upper portion of the runways. In this way I get a very compact construction, using theleast amount of metal, and also accomplish other objects, which are before stated, such as bringing the bolt in close proximity to the band and staves.

I find that it is advantageous to use a roller on each side of the bolt or rod E for each end of each band, as in this way I am enabled to bring the bolt into the position above described and also get a better bite or hold on the band, and especially soif perchance there is alittle diierence in the thickness of the sides of the end of the band.

With this construction the operation of my device will be readily understood, and the end of the band, as B', is inserted in the slot C7, and the roller F is in the position shown in dotted lines, which permits the ready insertion of the baud. Then the roller F is caused to assume the position approximately indicated in full lines in Fig. 2, and owing to the inclination of the top portion CS it bites or bears securely on top of the end of the band and presses it against the base portion C'. This can be done by gravity or by means of some proper instrument, which may be introduced into the opening between the parts C3 and C10, and thus the lug is secured to the end of the band when both lugs are properly secured. VThe bolt E is passed through the openings C5 in the two lugs and can be tightened in any suitable way, as by the nuts E', and it will be seenthat the bearing portions of the nuts are near the ends of the lugs adjacent to the rollers F F', where they bite upon the ends of the band, so that there is almost a direct pull upon the band at this point, avoiding the tendency to tilt above referred to. Moreover, the bolt being in the openings in the lugs which are located between the runways and nearly on a level therewith enables the bolt to be drawn close to the ends of the bands, and this further aids in accomplishing the results desired.

With this construction the bands can be securely tightened and held in position and the lugs project the least possible distance beyond the circumferance of the tank or other device to which they are applied, and at the same time there is the least amount of metal in accordance with the strength of the lugs, it being so distributed as to produce great strength without undue weight.

l. In a band-fastener, a lug having a slot for the reception of the end of the band, an opening for the reception .of a bolt, runways one on either side of said opening, and a roller mounted in each runway, substantially as described.

2. In a band-fastener, a lug having a slot for the reception of the end of the band, a centrally-arranged opening for the reception of a bolt, runways one on each side of said opening, a toe controlling each runway, anda roller mounted in each runway, substantially as described.

3. In a band-fastener, a lug having a slot for the reception of the end of the band, a longitudinal central opening for the reception of a bolt, inclined runways one on each side of said opening, and a roller mounted in each runway, substantially as described.

4. In a band-fastener, a lug having a longitudinal slot for the reception of the end of the band, a wall above the slot having an inciined face, an inclined top portion,`the wall and top portion forming runways one on each side of the central opening for the bolt, a roller mounted in each runway, and means for retaining the roller in position, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

GEORGE P. RASCK.
